It is important to use reliable resources. If you are using other sources other than ours please validate the authenticity. By all means validate ours as well. Do not be too quick to trust random sites. There are way too many stories of things gone wrong due to developers being too naive. Take charge!
A few things to look for when determining a reliable source. Check the credentials of the author. Are they accredited? Do they have formal knowledge/education? How long have they been in the field? Check the sites following. Do they have loyal users? Or do people come see the site and leave after finding something alarming?
